Selecting what you want to practice in Lesson Practice
Is there a way to select a specific group of lessons in the lesson practices? For instance, a lesson practice that focuses on just verbs, or one that tests you on all material learned up to the first "shortcut" after you've progressed past it. As far as I can tell, the lessons include all material learned up to your current area in the skill tree. I found a discussion on this here http://www.duolingo.com/comment/229656 but it's from 7 months ago. Sometimes revisiting one skill at a time is too time-consuming, and doing them all at once doesn't allow focus on anything specific.
